We describe the effect of blending poly(3-hexylthiophene) (P3HT) with Au nanoparticles (AuNPs) on the performance of organic thin-film transistors. To this end we have used AuNPs of two different sizes coated with chemisorbed SAMs of oligophenyl-thiols possessing increasing lengths. The electrical characteristics of the hybrid materials revealed changes in the field-effect mobility depending primarily on the AuNP size, as a result of the variable energy level of the coated metallic nanocluster and by the degree of modification of the P3HT crystalline structure.
我们描述了将聚(3-己基噻吩)(P3HT)与金纳米粒子(AuNPs)混合对有机薄膜晶体管性能的影响。为此,我们使用了两种不同尺寸的涂有化学吸附的寡聚苯硫醇 SAM 的 AuNPs,其长度逐渐增加。混合材料的电特性显示出随着 AuNP 尺寸的变化,场效应迁移率发生变化,这主要是由于涂覆的金属纳米团簇的能级变化以及 P3HT 结晶结构的改性程度不同所致。
